Imaging Seminar [Advanced Amateurs]
Imaging with a Mallincam Color Hyper Plus (MCHP)
by Neil Fleming, Friday & Saturday Nights, if clear, 8:00 p.m. - ??? [PDF
Near the Ash Dome, to the South of the McGregor Observatory in the main observing field.
A noted astrophotographer, specializing in the capture of very high-quality images from
light polluted locations, such as those in the Boston area, Neil Fleming will give a demonstration of his
work with the Mallincam Color Hyper Plus video camera. The Mallincam is a sensitive video camera used for
greatly increasing the effective aperture of your scope by allowing the capture of incoming light over
multiple seconds. With settings for 7, 14, 28 and 56 seconds, The Mallincam can capture, and display,
objects many times fainter than you can see through your eyepiece!
Although most observers stick to a real-time visual display of objects, it is possible to capture
incoming exposures, and either stack and process them later, or have software gather images as they come in
and stack them in real time! Fleming will set up his equipment and demonstrate the use of the MCHP, the real-time capture of images, as well as image

Saturday Technical Talk Schedule [Advanced Amateurs]
The purpose of the Saturday afternoon “technical talks” is to provide relatively advanced amateurs
a forum to discuss various projects that other relatively advanced amateurs are currently working on. While
everyone is welcome, of course, please do not be surprised to hear a lot of astronomical jargon, hear about
some very complex technical issues and maybe even see a few confusing equations. If you have a suggestion for
a subject for a technical during an upcoming convention please click
The Saturday afternoon program begins in the Flanders Pavilion at 1 p.m. [PDF
- "Autocollimation Testing"
by Richard Parker, 1:00 – 1:45
Autocollimation testing provides an easy to interpret null test for a parabolic
mirror, or any optical system that brings parallel incoming light to a focus. The test is fast and
accurate. Autocollimation testing is not new, but is being used or considered by an increasing number of
ATM’s today as the interest in better telescope optics and group mirror making workshops is increasing.
This talk will show the test concept and discuss: the requirements for an autocollimation flat mirror,
important test bench features, how good the test is, and recognizing proper alignment of the test
optics, and testing completed telescope assemblies. The similar Hindle sphere test for hyperboloids will
also be shown. Whether you are a new or seasoned user of the autocollimation test, you will not want to
miss this talk.
- "Recreating Galileo’s Original Telescopes to High Precision Museum Quality
Significance of these Instruments"
by Jim and Rhoda Morris, 2:00 – 2:45
There are only two known telescopes remaining of the 50 or more that Galileo built.
This presentation will describe our process for replicating high precision museum quality replicas of
both the leather covered "presentation" telescope and the paper covered "working" telescope housed at
the IMSS in Florence Italy. We will cover our processes for researching the known information on these
instruments, highlight discrepancies and describe their resolution by our visiting the originals to make
our own measurements and observations. These replicas are displayed at IMSS and other museum exhibits in
many countries especially as celebrations of the International Year of Astronomy. We will also discuss
how these telescopes are not just optical levers but truly magnificent instruments that serve as
excellent examples of 17th century technology and reflect the qualities that
are part of our creative heritage and human condition.
- "Exploring the Moon: The Apollo Astronaut Experience"
by Andrew Chaikin,
2:45 – 3:30
Andrew Chaikin, author of "A Man on the Moon," will discuss the experiences of the
Apollo lunar astronauts as they became the first humans to explore another world. His newest book,
"Voices from the Moon," written with Victoria Kohl, features excerpts from his extensive interviews with
23 of the 24 Apollo lunar astronauts. Chaikin's talk will be illustrated with recent, high-quality scans
of mission photography.
- "A Large Refracting Coronagraph for Solar Coronal Studies"
by Steven Tomczyk, 3:30 – 4:15
The detailed study of magnetic fields in the solar corona requires a telescope with
an objective of at least 1.5 meters, a very low level of scattered light, and a large field-of-view. We
believe that these requirements are best met by a coronagraph with a singlet lens objective which we are
now proposing to build. We will discuss science drivers for the large coronagraph and present the
results of engineering studies which show that a refracting telescope of this size is feasible with
- "Construction of a Maksutov-Newtonian as a First Maksutov, and Why"
by Gerry Logan, 4:15 – 5:00
Gerry Logan, who is a long time professional optician and amateur telescope maker, who specializes in
complicated telescope designs, will discuss the benefits of constructing a Maksutov telescope and the
specific benefits of the Maksutov-Newtonian design.
There will be several talks during the convention which will be geared for people who are new
to amateur astronomy and the Stellafane convention: [PDF version]
- Fri 4:00 pm and Sat 12:30pm: Solar System Walk behind the pink Clubhouse by Tom
To illustrate the vast size of outer space, the Springfield Telescope Makers constructed a scale model of
the solar system, based on the Sun being 12 inches in diameter. At that scale, the Earth would be approximately
1/10 of an inch in diameter and 107 feet from the Sun. Jupiter would be 1.2 inches in diameter and approximately
560 feet from the Sun.
The “Solar System Walk” starts up behind the Pink Clubhouse and proceeds down the road going towards the
Stellafane camping area. At the appropriate distance, from the scale model of the Sun, there are stations with
the appropriate planet, built to scale, and a short description of each planet. The Solar System walk can be
taken at any time during the convention. However a guided walk is available at the times mentioned above when
Thomas Gorka will provide additional information about the “Solar System Walk” and each particular planet. The
walk takes approximately 3/4 of an hour, if you walk all the way to the planet Neptune, with a total distance
of 3232 ft, or a little over ½ of a mile.
- Fri 5 pm: Stellafane for Beginners in the McGregor Observatory by Kim
Keegan & Dennis Cassia
Are you familiar with these terms: “The Pink”, “Tent Talks” or “The Turret”? If not, or if this is your
first Stellafane or if you are retuning and want to learn more about who the Springfield telescope Makers
are, as well as what is going on during this convention, then this presentation is for you. Topics include,
but are not limited to: A short history of Stellafane, a description of our site including the buildings
and landmarks, descriptions of the scheduled talks and activities, services available at Stellafane, local
services off site, etc. in addition to answering any questions you may have about the convention.
- Fri 9 pm: Harrington on Binoculars by Phil Harrington in the McGregor
Binoculars are a great way to enjoy the beauty of the summer sky, whether you are a beginner or a
veteran stargazer. In this presentation, Phil Harrington will define several binocular-related terms and
discuss consumer tips to help the audience weed out astronomically worthy binoculars from the vast ocean
of models currently sold worldwide. Afterward, join Phil outside for a tour of the night sky through
- Sat 11 am: Tour of the Russell Porter Turret Telescope by Brad Vietje
meet at the Turret Telescope
Located at the summit of Breezy Hill, immediately to the North of the Stellafane Pink Clubhouse, The
Russell Porter Turret Telescope is one of three known “turret telescopes”. The primary advantage of this
type of telescope is that the observers are inside of the observatory building, protected from the cold
temperatures of long winter nights and biting mosquitoes of summer nights. Brad Vietje, member and past
president of the Springfield Telescope Makers, will talk about the history of the Turret Telescope,
demonstrate how the telescope is used and observe the Sun, if the weather permits and the Sun obliges by
displaying some sunspots.
- Sat 10:30 am: Telescope Field Walk by John Vogt and Carl Malikowski
meet in front of the Pink Clubhouse
During the “Telescope Field Walk”, John Vogt, David Britz and David Groski, all experienced Amateur Telescope
Makers, will guide small groups through the fields around the Pink Clubhouse, where the telescopes that
will be participating in the mechanical competition will be set up. They will describe the various types
of optical designs and mounting configurations that will be on display, point out the subtle details that
go into award winning telescopes and be available to answer your questions.
- Sat 1:30 pm: Dipper Full of Stars: A Tour of the Night Sky by Richard
in the McGregor Observatory
Using stunning images of constellations, planets, and celestial objects, Richard Sanderson will lead
an interpretive tour of the summer nighttime sky. He will describe how the sky appears to move throughout
the night and from season to season, and explain the significance of the North Star. He will speculate about
life on other worlds and show many of the prominent summer constellations. The presentation is aimed
at beginners of all ages.
- Sat 5 pm: An Introduction to Telescopes for All Ages by Sue & Alan French
in the McGregor
Adults and youngsters often become interested in astronomy and acquiring a telescope for exploring
the heavens. With the plethora of telescopes on the market, buying your first telescope, or a telescope
for a child, can be intimidating. In this program Sue and Alan French will cover telescope basics
(types, mounts, and eyepieces), telescopes suitable for children, and introduce you to observing and
finding sights in the night sky.
- Sat 10 pm: Discover and Enjoy the Sky by John Briggs at the McGregor Observatory.
The beauty of the night sky is a driving motivation for telescope making, the Stellafane convention and
astronomy in general. John W. Briggs, a physics & astronomy instructor at Clay Science Center, will show
how to become oriented in the sky using popular references, recent new software and other tools of astronomy.
The presentation will be appropriate for all ages. Weather permitting, after the program the group will
use the historic 5-inch Alvan Clark refractor, originally installed at Abbot Academy in 1875.
There will be four 1-hour astronomy workshops for children held in the McGregor Observatory
during the 2009 Stellafane Convention (Friday, August 14TH at 11:00 a.m. & 3:00 p.m. and Saturday, August
15TH at 11:00 a.m. & 3:00 p.m.). These astronomy workshops have been held at the Stellafane convention
since 1995. Led by Dr. Kristine Larsen, of Central CT State University and member of the Springfield
Telescope Makers, each of the four 1-hour workshops includes several activities geared for children ages 5 -
12. Younger children are welcome but will need help from a parent. Each workshop has a different
astronomical theme. Please inquire at the McGregor Observatory for the theme for each specific workshop. Due
to space limitations, each workshop is limited to 25 children on a first-come basis. [PDF
